对ω-氯代氧杂全氟羟酸(ClCF)与溴化辛基三甲铵(C8N)混合体系的表面活性和泡添性质进行了研究。溶液表面张力测定的结果表明, ClCF及其混合体系有很低的监界胶团浓度(cmc)和γcmc值, 即有很高的表面活性。ClCF溶液有很好的起泡性能, 但ClCF-C8N混合体系与一般正负高子表面活性剂混合体系迥异, 显示出ω-氯代结构的特殊影响。

The surface activities and foaming performences of ω-chloro, γ -oxaperfluorodecanoic acid (ClCF) and its mixture with octyltrimethylammonium bromide (C8N) have been investigated. ClCF and the mixture show high surface activity with very low cmc and γcmc. The aqueous solution of ClCF performs good foaming ability. However, the mixture of ClCF-C8N system is quite different from that of perfluorocarboxylic acid and C8N system showing the particular effect of the ω-chloro group.

Key words: SURFACE ACTIVITY, SURFACE TENSION
